AT&T数字加密处理器和随机数字发生器据《Electronics Design》1986年34卷30期报道,现在唯有AT&T生产的T7000A数字加密处理器能提供四种方式的DES加密,包括1、8或64比特密码反馈。四种片上密钥和初始值寄存器可以对单一数据流进行高达四次的加密,这样就可达到最大的保密度:或者,如果你愿意的话,还可对四个数据流同时进行加密,然后多路复用。由于采用了低功耗CMOS技术,而使T7000A具有高达1.8Mbps的吞吐量。AT&T AT & T Digital Encryption Processors and Random Number Generators According to Electronics Design, Volume 34, Issue 30, 1986, only the T7000A Digital Encryption Processor from AT & T offers four ways of DES encryption, including 1, 8, or 64 bits Password feedback Four on-chip keys and initial value registers enable up to four encryptions of a single data stream for maximum security: or, if you wish, encrypt up to four simultaneous streams and then multiply Road reuse. The T7000A delivers up to 1.8 Mbps throughput due to the low power CMOS technology. AT & T
